如何取得磁盘序列号？
调用API函数 GetVolumeInformation。 API声明： Declare Function GetVolumeInformation Lib "kernel32" _ Alias "GetVolumeInformationA" _ (ByVal lpRootPathName As String, _ ByVal lpVolumeNameBuffer As String, _ ByVal nVolumeNameSize As Long, _ lpVolumeSerialNumber As Long, _ lpMaximumComponentLength As Long, _ lpFileSystemFlags As Long, _ ByVal lpFileSystemNameBuffer As String, _ ByVal nFileSystemNameSize As Long) As Long 程序: Private Sub Form_Load() Dim sDriveLetter As String Dim RetVal As Long Dim lpName As String Dim nSize As Long Dim nSerial As Long Dim lpMaxComp As Long Dim nFileFlags As Long Dim lpFileName As String lpName = Space(255) lpFileName = Space(255) nSize = 255 sDriveLetter = "a:\" ’这里你可以指定任何盘号 RetVal = GetVolumeInformation(sDriveLetter, lpName, _ nSize, nSerial, lpMaxComp, nFileFlags, lpFileName, nSize) '你可以看出,不仅能得到序列号,还可以得到其他很多信息 If RetVal = 0 Then '这里是你的错误处理代码 Exit Sub 'Quit the subroutine Else lblDriveSerial.Caption = CStr(nSerial) '假定你已经建立了这个标签,将在标签上显示序列号. End If End Sub
